SHOVEL-BLADE.

Specification of Letters Patent.

Patented June 6, 1911.

To all whom it may concern:

Be it known that we, ALBERT HELT and BENJAMIN HnLT, citizens of theUnited States, residing in Pittsford township, in

the county of Butler and State of Iowa, have invented a new and usefulShovel-Blade, of which the following is a specification.

The invention relates to a shovel blade for corn plows and cultivators.

The object of the present invention is to improve the construction ofshovel blades, and to provide a simple, inexpensive and efiicient shovelblade, designed principally for use on corn plows, and capable of beingarranged for throwing the soil either toward or from the corn, or forcutting Weeds at a uniform depth between the rows, and capable also ofbeing adjusted to run either deep or shallow.

Another object of the invention is to provide a shovel blade of thischaracter, which will not cut the roots of the corn and which will beadapted to be applied to plows having standards of different sizes.

With these and other objects in view, the invention consists in theconstruction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawing, and pointed out in the claimshereto appended; it being understood that various changes in the form,proportion, size and minor details of construction, within the scope ofthe claim, may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.

In the drawing :Figure 1 is a front elevation of a shovel blade,constructed in accordance with this invention, the blade being shown ina central position in full lines and tilted in dotted lines. Fig. 2 is arear elevation of the shovel blade. Fig. 3 is a central verticalsectional view. Fig. 1 is a horizontal sectional view on the line 4.& ofFig. 1.

Like numerals of reference designate corresponding parts in all thefigures of the drawing.

1 designates a blade of substantially trapezoidal form, constructed ofsuitable metal and having parallel upper and lower edges and upwardlyconverging side edges. It is provided with a lower cutting edge 2 and ithas a slight curvature from top to bottom and a uniform upward taper,and the straight side and bottom edges form points at each side or endof the blade. The blade is pivoted centrally of its upper portion to ashank 3 by a bolt 4c provided with a squared head tapered and securedwithin a counter-sunk opening 5 in the blade, as clearly illustrated inFig. 3 of the drawing. The bolt, which has its head flush with the frontor outer face of the blade, pierces the shank and is equipped with a nut6, a plurality of washers 7 being preferably interosed between the nutand the shank. The lade is adapted to be arranged in a central positionwith its upper and lower edges horizontal, and it is adapted to beadjusted vertically by the means hereinafter described, so as to run atthe desired depth, and it is capable when in such position of cuttingthe weeds at a uniform depth between the rows. The pivot bolt alsopermits the blade to be tilted, as illustrated in dotted lines in Fig. 1of the drawing, and the lower corner or point may be arranged at eitherside or end of the blade for adjusting the same to throw the soil eithertoward or from the corn.

The shank 3, which is constructed of suitable sheet metal and which isstamped or otherwise formed, consists of a lower substantially fiatportion 8, an intermediate transversely bowed upwardly tapered portion9, and a transversely curved upper portion 10 having flat lateralextensions 11. The upper portion of the shank cooperates with a rearclamping plate 12, consisting of a central transversely curved portionand flat lateral extensions 13, arranged opposite the lateral extensions11 of the shank and connected with the same by bolts 14. Thetransversely curved upper portion of the shank and the curved co-actingportion of the clamping plate are adapted to fit against the front andrear portions of the standard of a plow or cultivator, and they areadjusted by means of the said bolt to fit standards of difierent sizes,and also to permit the blade to be arranged at different elevations, soas to run at the required depth. The bolts 14 are equipped with nuts 15and washers 16 are interposed between the nuts and the clamping plate.

Having thus fully described our invention, what we claim as new anddesire to secure by Letters Patent, is

A device of the class described including a shank constructed of sheetmetal and consisting of a substantially flat lower portion, anintermediate upwardly tapered transversely bowed portion, and atransversely curved top attaching portion having fiat lateralextensions, a blade fitted against the lower fiat portion of the shankand pivoted to the same so as to be adjusted to form a lower projectingpoint at either side of the blade, a rear clamping plate consisting of acurved intermediate portion to co-act with the upper attaching portionof the shank, and flat laterally projecting portions arranged oppositethose of said shank, and fastening means adjustably connecting thelaterally extending portions.

In testimony that we claim the foregoing as our own, we have heretoaffixed our signatures in the presence of two witnesses.
